The anatomic relationship of body and posterior horn of medial meniscus and joint capsule
•Axial view illustration of the anatomic relationships of the posterior horn of the medial meniscus (PHMM), posterior capsule, posterior oblique ligament (POL), deep medial collateral ligament (MCL), and semimembranosus tendon.
•The attachment of the MM to the joint capsule is more rigid, making the MM more susceptible to injury than the LM.
•The PHMM had a mean length of 21.3 ± 2.0 mm (range, 17.6-24.5 mm), essentially confluent with the entire length of the posterior capsule.
•The posterior meniscocapsular attachment had a mean ± SD length of 20.2 ± 6.0 mm (range, 11.3-33.2 mm)
•The dMCL had a broad, firm attachment to the midbody of the medial meniscus.
The dMCL 1 meniscofemoral attachment blended with the POL meniscofemoral attachment posteriorly and with the anteromedial capsule anteriorly.
•The meniscal attachment of the POL was a direct expansion of the posteromedial capsule.
•The semimembranosus-meniscal attachment branched from the anterior arm of the semimembranosus and was located between the posterior meniscotibial ligament and the meniscotibial POL attachments
